The research work discribed in this paper is aimed at analyzing and controlling noise of a new type of high sped lathe.The main characteristic of this lathe designed with a separate model, which ensures a high rotational precision and good dynamic , is that.its headstock was performance to spindle.The lathe is with a highest spindle rotational speed of 2000 r.p.m. and main motor power of likll.According to the empirical formulall] obtained from statistical ' ; Proc.l.O.A.
